> This is not true. Even though blockchain is decentralized there could be a single chain/few chains of truth if you want to convert it to real money. And that chain could only be the one that would be approved by coinbase, bitfinex etc I don't think this is fair to say because what you are describing here is a situation that is occuring off a blockchain or one that is occurring on the blockchain but where the individual transacting has chosen to allow someone to censor their transactions. Your overall point that a decentralised system consists of centralised links that can and will be attacked by a hostile entity or node(s) is valid though.
